Seems to me that the three working together did everything right, except try to load the jury with votes for them to win.
Angela by far has done the worst job. She pisses off everyone on their way out the door, and if you recall early in the game, she was absolutely wrong on her accusations. 1000 to 1 odds of winning it all.
Tyler had deals with everyone and will have to face the jury and explain why he deserves their vote. This is one of those times where it depends on whether jury members were fans and respect the game, or are just pissed. 4 to 1 odds of winning it all as it all banks on his sitting next to Angela in the final two, or continuing to be the golden tongued master he has been all game.
Kaycee can show she was a comp monster AND she managed to keep from pissing off anyone. She let Tyler and Angela due and say all the mean stuff. 2 to 1 odds on her winning it all.
JC always said nice things to the people as they were voted out in his goodbye videos. He didn't seem to offend anyone (other than Bayleigh...is she in the jury?). He was likeable and most important, had no blood on his hands. In my opinion, this seems like a mostly petty jury and this will carry weight. 15 to 1 odds of winning it all because I don't think any of the other three would want to go up against him, so he'll have to do it himself, then be sitting next to Angela.
